  1. 21. Treatment of per- and polyfluoroalkylsubstance (PFAS)-contaminated waterusing aeration foam collection

    University essay from

    Author : Ylva Kjellgren; [2020]
    Keywords : PFAS; aeration foam collection; landfill leachate treatment; WWTP;

    Abstract : Landfills are potential sources for PFASs and treatment techniques for landfill leachate are urgently needed. Foam fractionation is an aeration technique which utilizes the tendency of PFASs to escape the liquid phase and build foam. The foam is harvested and with it the contamination. READ MORE

  3. 22. The effect of spent mushroom (Agaricus bisporus) compost on the indigenous rhizosphere microbiota in strawberry cultivation

    University essay from SLU/Dept. of Agricultural Biosystems and Techology

    Author : Hani Elaamer; [2020]
    Keywords : Trichoderma spp; Actinomyces spp; Pseudomonas spp; Bacillus spp;

    Abstract : Spent mushroom compost (SMC) is a by-product of mushroom cultivation with the potential to be used in the cultivation system to suppress plant pathogens, enhance water holding capacity, increase soil water aeration and to improve the soil structure through the input of organic matter and additional nutrients. The electric conductivity (EC) as well as pH recorded high values in the SMC, which is a challenge for its application in food production systems. READ MORE

  4. 23. Partial denitrification as nitrite provider for mainstream anammox

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Felix Wallin Holmin; [2020]
    Keywords : Water engineering; Environmental engineering; Mainstream anammox; Partial denitrification; PDA; MBBR; Nitrogen removal; Vattenförsörjningsteknik; Avloppsteknik; Technology and Engineering;

    Abstract : In traditional wastewater treatment, nitrogen is removed through the biological process combination of nitrification and denitrification. Although it is a well-established method, the need for aeration and possible addition of an external carbon source results in it being an energy-negative and costly process, thus making alternative methods for nitrogen removal compelling to examine.

  5. 24. Mainstream Deammonification process monitoring by bacterial activity tests

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Andrea Carranza Muñoz; [2020]
    Keywords : Ammonia Oxidizing Bacteria AOB ; Anammox; Bacterial activity; Deammonification; Heterotrophic bacteria; IFAS; Mainstream wastewater; Nitrite Oxidizing Bacteria NOB ; Nitrogen Removal.;

    Abstract : Deammonification is a widely used technology for side stream treatment with rich ammonium streams at relatively high temperatures, such as, the reject water coming from dewatering units in treatment of digested sludge and industrial wastewaters. The deammonification process has lower operational costs than conventional systems, consumes less energy, enables the increase of biogas production and it is easy to implement. READ MORE

  6. 25. Olika filtermaterial vid jordbruksdränering

    University essay from SLU/Dept. of Soil and Environment

    Author : Hanna Falk; [2019]
    Keywords : dräneringsfilter; mineralfilter; organiska filter; syntetiska filter;

    Abstract : Drainage of arable land creates a better soil structure and a better aeration of the soil profile. Some fields are naturally drained, while others are dependent on drainage to create good cultivation conditions. Subsurface drainage is the most common method used to artificially drain arable land.
